TWOHPLY INGRAIN CARPET FABRIC.

SPECIFICATION forming part of Letters Patent No. 610,742, dated September 13, 1898 Application filed March 5, 1897. Serial No. 626,071. (Specimens.)

To all whom t may concern.'

Be it known that I, HARRY HARDWICK, a citizen of the United States, residing at Philadelphia, county of Philadelphia, and StateV of Pennsylvania, have invented a new and useful Improvement in Two-PlyIngrain Carpet Fabrics, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which form a part of this specification.

My invention has for its object the production of a fabric having` by its formation a capacity for increased effects upon the surface and also a greater wearing-surface.

There have been made prior to my invention two-ply ingrain carpet fabrics in which there were a set of warps light in weight, which were used for the binding of the wefts, and a heavier set of warps, which were used intermediate of the plies, acting as stuffers.

The most common construction of two-ply ingrain carpet fabrics is to produce all the color effects and design upon the surface by means of the wefts.

In my invention I take advantage of the heavier warps not only to act as stuffers between the plies, but by bringing them to the face in places I can get an increased effect by reason of the heavy warps overlying the weft at these places, and by reversing this operation I make the plies of the fabric even as to this construction and increase the wearing capacity. In places where I do not bring these heavy warps to the surface or back of the fabric I leave them between the plies to act as stuffers. In my construction these warps are colored, so that when they appear upon the surface they will add a color effect to the warp, it being heavier than the ordinary binder-warp.

Speaking generally, my invention consists of a two ply ingrain carpet fabric having wefts in sets and two sets of warps, the warp in one set differing in size from the warp of the other set, and in which the heavy warp in places overlies the weft and in other places the light warp overlies the weft, thus using at times the heavy and at other times the light warp to act as binders. W'ith this construction where the heavy warps are not on either face of .the fabric they lie in the center and act as stuffers. I can also in addition to the heavy warp whichv at times overlies the weft use other heavy warp which throughout lies between the plies and acts throughout the fabric as a stuffer in some places alone and in others in conjunction with the other heavy warp.

I will now describe the embodiment of my invention illustrated in the drawings, and then particularly point out the invention in the claims.

Figure 1 represents one embodiment of my invention. Fig. 2 represents a view similar to Fig. 1,with one stuffer-warp of Figl eliminated.

The drawings represent a section taken along the fabric upon the warp. The wefts are denoted by their color-letter and the number denoting the order of throw. Y

In Fig. l wefts are thrown in the order B, black, 1; O, olive, 2; R, red, 3; W, white, 4. The warps are of two sets, c and d being warps light in weight, while e, f, and g, the other set, are heavy in weight. The warps c, C23, e, and f being preferably colored, the warp g need not necessarily be colored. The fabric is divided up into the sections denoted between the respective dotted lines 5 28 and show the different effects which may appear upon the fabric.

As shown in sections 5 10, the Wefts upon the face and the back are bound by the warps, c and d being the light warps, while the heavy warps c and f lie between the plies, acting as stuffers. In sections l1 16 the heavy warps e and fwbind the wefts of one ply, (the back,) and thus a heavy warp overlies the weft, while the light warps c and d bind the wefts of the other ply, (the face.)

In sections 17 22 the reverse is shown in that the heavy warps c and f bind the wefts upon the reverse ply to that spoken of, and thus a heavy warp again overlies the weft, while the light warps c and d bind the wefts of the other ply. Y

In sections 23 28 the weft on the face 'and back are bound by the heavy warp, thelight warp lying between the plies; Throughout the warp g lies between the plies andactsas a stuffer. In the place where the heavy warps c and f lie between the plies they, in conjunc tion with the warp g, act as stuffers.

It can be readily seen from this construe tion that a heavier and stronger fabric will inure; further, that by bringing the heavy Warps over the Wefts in place on the fabric they, being heavier than the ordinary binder- Warp, will give a color effect of Warp to the face of which the ordinary ingrain two-ply carpet is not capable.

The construction of Fig. 2 is the same as Fig. l, except the Warp g is omitted. In this construction stuffers exist only when the Warps e and f lie between the plies.

Having now fully described my invention, what I claim, and desire to protect by Letters Patent, is

l. A two-ply ngrain carpet fabric having wefts in sets, and iight and heavy Warp, and

the plies throughout the fabric.

In testimony of which invention I have hereunto set my hand.

HARRY HARDVVICK.
